This isn't a bug. You need to name the .pyx and .pxd files
using the full dotted name that the module will eventually
have in the package hierarchy. For example, a module called
spam that will reside in a package called foo should have
source files named "foo.spam.pyx" and "foo.spam.pxd".

This is not officially documented yet, because I haven't
decided on the best way of dealing with the issue. But that's
how it currently works.

I wouldn't recommend changing that, because I can't be sure
it won't have some other undesirable effect. It's safer to
use the naming scheme described above.
